Shock Wave by John Sandford.
John Sandford is one of myBook My Favorites authors. If you are a resident you too can sign up for Book My Favorites. This book is one of his Virgil Flowers series. Virgil Flowers is a spinoff of the Lucas Davenport books. Virgil Flowers is a detective in the Minneapolis area and works for Lucas Davenport. In this mystery someone is blowing up stuff and people, with bombs. Virgil is called in to solve the mystery. The readability of the book is more of an immersion than a finding out who did it. Yeah, Virgil solves the crime but the author brings Virgil to life. When Virgil will be up late at night he takes a nap in the afternoon, he eats breakfast (and you get to read what he orders). You feel like you are there, an unseen watcher. Virgil is a holdover from the 60's person, always wears a t shirt from some band. The people he interacts with always comment on his penchant for wearing these t shirts. Women for some reason desire him and he usually winds up woo'ing one of them.
PyeMart is planning to open a store in a small town. By opening this store it will destroy many small businesses, they just will not be able to compete. The rain runoff from the huge parking lot is threatening the river. PyeMart is a made up name but when Walmart came to Portage we had some of the same issues. There were lots of articles about how the runoff ruined Portage Creek. So, I'm thinking some of this is a change the name so we don't get sued, make a statement about big business and the environment, take a what if scenario and make a mystery of it. It's a good read.
